She opted to join Team Cee Lo over Team Christina Aguilera and Team Adam Levine, who had both expressed an interest in working with her. She told reporters on a recent conference call that although she had also considered choosing Aguilera, she eventually decided to join the 'Forget You' star.

"I think when I was choosing I was thinking as a businesswoman," she explained. "I love Christina; I grew up listening to Christina. She is one of my idols, same with Adam Levine.

"I know what Cee Lo really likes and the songs he sings and his music nowadays. I love his music and his style. I think he has a unique voice and he's also a producer. The way he spoke and said, 'You sang this song and your clarity was amazing' and all the compliments he was giving, I could tell he was truly passionate to work with me."

Prior to her audition on The Voice, the singer had already found fame via YouTube in Europe with her video for 'Masquerade'.

"It was a random idea to do the YouTube video," she said. "My producers at the time owned the rights to the song and wanted to do a video to see how many hits it would get. They made the song a club song and made a video to see how may hits it got. In four days it got a million viewers which was kind of surprising because it happened so quickly."

The 20-year-old also said that she had been surprised that some people had formed the wrong opinion about her following her audition, saying: "I have been getting some negative comments saying I might be too cocky or conceited. I'm pretty sure the [other contestants] would agree that if they knew me, that's not the truth."

Fellow singer Frenchie Davis, a member of Team Christina, agreed, describing Rey, who had been her roommate during the process, as a "sweet, sweet girl". She told reporters that Rey was an example of someone who is both beautiful and talented.

"Let's face it, the industry is full of beautiful girls who might not necessary be great singers," said Davis. "Kelsey is a gorgeous girl and people probably do look at her and assume that's what she is and that she doesn't have any musical talent. But I think she's an excellent example of how this show works in the reverse. Kelsey isn't just a pretty face. She has a heart of gold. She's a smart girl and she's talented."

As for what sort of music Rey would like to make in the future, she said: "It might come as a surprise to everybody that yes, I do love pop music and think I fit in with the pop genre, but I like pop with flair.

"I like soul music and blues. I really like to sing from the heart and I like big band stuff. I would like to eventually someday have a band behind me and I would love to have an all-girl band which is kind of crazy but I think it would be cool. I think that's another reason I chose Cee Lo."
